- Atomic structure
- Nucleus
- Contains protons and neurtons
- Protons have a positive charge
- Both have the same mass
- Neutrons have no charge
- Contains protons and neurtons
- Protons have a positive charge
- Both have the same mass
- Neutrons have no charge
- Neutrons have no charge
- Both have the same mass
- Protons have a positive charge
- Contains protons and neurtons
- Neutrons have no charge
- Both have the same mass
- Protons have a positive charge
- Found at the centre of an atom
- Extremely dense, accounts for almost all of the atom's mass
- Only a small volume
- Contains protons and neurtons
- Electrons
- Electrons orbit the nucleus in shells
- They have a negative charge
- An electron is 1/2000 the relative mass of a proton or neutron
- Isotopes
- Atoms of the same element with different numbers of neutrons
- Same number of protons and electrons
- An element's mass number is based of the relative abundance of its isotopes
- Different isotopes of the same element react in the same way
- Neutrons don't effect chemical reactivity
- Atoms of the same element with different numbers of neutrons
- Ions
- A neutral atom has the same number of electrons as porotons
- Losing or gaining electrons
- To become stable
- Unbalanced numbers of electrons and protons
- Charges don't cancel out
- Most of the volume of an atom consists of the empty space between the nucleus and shells
